Hi, It seems that ddclient settings are being synced to the secondary node even those ddclient is not checked in HA settings. It seems that the NAT setting is causing this. Once NAT is uncheck from syncing, ddclient settings are no longer synced.
Edit: Seems this issue has been fixed: https://github.com/opnsense/core/commit/7e994cab

We will issue this with 24.1.1 early next week.
Cheers,
